[artist id="501686"]Britney Spears[/artist] is a month away from the release of Femme Fatale, and nearly every day, she's teasing fans with samples of some of the songs on the album, including the latest, her song with will.i.am, "The Big Fat Bass." Now, longtime collaborator Rodney Jerkins is opening up about hitting the studio with Spears.

"Britney's always great to work with. I've worked with Britney for 12, 13 years now," he told MTV News. "It's always great to work with someone when you work with someone time and time again; it's always great, and it always gets better. And just to see her evolve as an artist, it's an amazing, amazing thing."

Jerkins worked with Spears in the past on "Overprotected (Darkchild Remix)" and "I Love Rock 'n' Roll" in the early 2000s, as well as her leaked version of Lady Gaga's "Telephone," when she was recording Circus.

This time around, he said Spears knows exactly what she wants musically on the album. "She was very hands-on. She had a lot of ideas for me," he said. "She's great. She gets it. She is a top-notch veteran pro at this now."

She might be getting some help from Jerkins, but Dr. Luke and Max Martin are executive-producing the album, and Jerkins had nothing but the best to say about the production team. "I never spoke to them, [but] those guys are just great, and the stuff that they've been doing is just really, really great stuff," he said. "I'm sure with their hands on it, it's great."

Spears herself has described the album as "moody, edgy pop with A LOT of energy," hinting that many of the songs will be uptempo, and Jerkins noted that the songs he's been writing for her have certainly fit that label. "I know the songs that I do are uptempo," he said. "The stuff I've done, I think, will kind of shock people. I got a chance to go out my box a little bit too. She's great. Britney's just awesome."
